So You Want A Watertight Envelope?

Recon recently reviewed specifications on a large local goverment building project that includes installation of Aluminum Windows, Aluminum Storefronts and Aluminum Curtainwall. The only language in them that attempts to confirm the design goal of building a watertight building is the lonely section quoted below. It was found deep inside the Division 8 Specifications:

************************************************************************

1.08 FIELD TESTS

A. Field Testing: Owner may employ an independent testing agency to perform tests on in-place
curtain wall systems and components. Cooperate with testing agency at all times during field
tests.

1. Leakage: Tests will generally include a prolonged water spray test similar to AAMA 502.
Any uncontrolled leakage within the curtain wall system or between the curtain wall
system and adjacent construction will be considered a failure.

2. Failures: Contractor shall pay for all remedial work and all retesting required because of
failures.

************************************************************************

Despite a coastal location, with a history of tropical storm winds and rainfall, the building's most vulnerable portion of the envelope is largely being left to chance by not requiring independent field testing of all types of the installed fenestration in the building.

The cost of testing is minimal when compared to the resolution of problems that typically follow moisture intrusion events in buildings.
